    Description

      The subclass of this test are creating ssl servers independently of DefaultServer and are causing the issue. Even though on teardown the test closes the servers, it mistakenly verifies if worker is shutdown, while it should verify if it is terminated. There is a small window of time where shutdown is requested but the worker is not terminated yet. And, because we are incrementing latch count only if the worker is not shutdown, we also skip the sleep that serves as a double protection against the "Address alread in use" issue.

          is caused by

          Sub-task - The sub-task of the issue UNDERTOW-1960 Address already in use in LoadBalancingProxy test cases

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
